It’s a dead horse, but my own anecdotal experience over the last 30 years in the Boulder Mountains is that of mule deer age class collapse.
I agree with
@Elky Welky that Montana is an “opportunity state”, and I actually hope we continue to view opportunity as a virtue. I have shot my fair share of two points, hell I have
written about it on here. Next year my 10 year old boy, the most enthusiastic human I have ever known, will be hunting deer. Knowing what is out on the landscape here, it is likely and I will view it as a blessing, if we will kill a 2.5 year old mule deer.
We could retain an enormous pile of chance – our status as a state of opportunity – and still reign things in a bit. I think a successful discussion we could have with most Montanans would not be that of drastic change, but one of balance. If we shifted our rifle season to be one week earlier, and removed the last week, I believe it would have a meaningful effect on the structure of age class in many HDs across our state. A guy would still have 5 weeks to chase the bucks. Just have the season end the first week of Nov.
It's not judgement, nor a desire for “trophies”. It's actually deeper than that. If I speak to the hills I grew up in alone, I can wager the story rhymes with others across divides. What do we really know about mule deer in these mountains? When we don't allow deer to ever "get old", which in Montana really just means mature reasonably, we are potentially missing out on knowledge. Perhaps it is behavior, or dynamics, or some other gift the observer ain’t getting, but it's hard not believe that there is a really fascinating aspect of "deerness" that is void from the landscape. Maybe even a wisdom. Much the same as how incomplete a study of some human civilization would be if none of its members ever surpassed the age of 25. In terms of Odocoileus hemionus, the landscape is littered with children and teens, and bare of men.
It's one reason the Elkhorns, as imperfect as they are, have spirituality in them to me. There’s likely elk in that range right now, that were born when George W. Bush was still president. Maybe we don’t need that level of depth, but in the HD where I live, I am skeptical a deer exists that is as old as my 5 year old son.
